A study by scientists from the New York University’s School of Medicine published in September 2012 found elevated levels of a common food contact substance, bisphenol A (BPA), to be associated with a higher risk for being overweight in children and adolescents. The study used nationally representative data from the National Health and Nutrition Examination Survey (NHANES) study collected in 6 to 19 year old US inhabitants. The study’s design does not permit conclusions regarding causation, however biological plausible explanations of how BPA may cause overweight or obesity do exist, making the study relevant and highlighting the need for further research.
